Maintaining Storm Drains
Join volunteers across the city to maintain storm drains, a critical part of our utility infrastructure.
Sign up to adopt a storm drain near your home or work. By registering, you commit to keeping the drain surface clear of leaves and other debris year round.
If you have any questions, please contact us at firstname.lastname@example.org or at (206) 233-7187.
Why should I adopt a drain?
- Prevent flooding in your neighborhood by keeping drains free of debris.
- Prevent pollutants from entering streams, creeks and Puget Sound, which protects fish and other wildlife.
- Help the city maintain our infrastructure, especially during fall months when rain increases and falling leaves block drains.
If you adopt a drain, SPU may contact you to notify you of anticipated storms and flood events.
Is your storm drain not shown on the map?
Use our mapping tool to zoom in and add your drain by pointing to the approximate location on the map.
How to identify a drain
Though there are several types of storm drains, most drains are located in or next to the curb and have a metal grate to prevent people and debris from falling in. They can be rectangular or circular. Storm drains often will be stenciled with text such as:
- Dump No Waste. Drains to Stream, Lake or Bay.
- Only Rain Down the Drain. Puget Sound Starts Here.
Sanitary sewers, which usually have solid manhole covers, are NOT storm drains.
If a storm drain near your location is grayed out on the map, it could be:
- unavailable because it is not owned by SPU
- a storm drain that only SPU crews should maintain
Clear your drain only if it is safe. If the drain is still clogged after you’ve removed the surface debris, use our Drain Report Form or call our drainage problem hotline at (206) 386-1800 to report it.
- Clear only drains next to the curb. Clear from curbside, not out in the street.
- Watch out for traffic. Don’t clear drains that are in the middle of a street.
- Be careful of standing water to avoid slipping or stepping on sharp objects.
- If children are helping, make sure adults are supervising.
- Don’t try to lift storm drain grates. They are very heavy.
- Let our crews handle garbage or any hazards in the catch basin. Clear surface debris only.
